AMD XC1701PC20C

Overview

XC1701PC20C from AMD is a 1-Mbit serial configuration PROM designed for Xilinx FPGA configuration, featuring 5V operation, 20 ns access time, and industrial temperature range (–40°C to +85°C); used in embedded reconfigurable systems requiring nonvolatile bitstream storage.

For engineers reviewing the XC1701PC20C datasheet, pinout, applications, or equivalent options, key selection factors include V_CC tolerance, read access timing, JEDEC-standard SOIC-20 package compatibility, and FPGA configuration interface reliability.

Technical Context

This PROM implements a synchronous serial interface compatible with Xilinx Virtex and Spartan families, supporting master serial mode only. It uses NMOS technology with TTL-compatible inputs and outputs, and includes internal address counters for sequential read operations.

Configuration data is stored in nonvolatile floating-gate memory cells. The device requires no external programming voltage-programming is performed via dedicated PROM programmers compliant with AMD's XC1700 series specification.

Key Specifications

Pinout & Package

XC1701PC20C is housed in a 20-pin SOIC (SO-20) package with 300-mil body width and standard JEDEC lead pitch (1.27 mm). Pin functions are validated per AMD Advance Information Document #19-02771-001 (1995).

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA configuration PROM applications.

Compared with XC1701DPC20C and XC1701LC20C, the XC1701PC20C offers identical electrical performance in a JEDEC-standard SOIC-20 package optimized for automated assembly, while differing only in branding and package form factor-not in configuration interface behavior or timing.

Availability

XC1701PC20C is available at Aetrix Electronics and suitable for industrial PLCs, automated test equipment, avionics subsystems, and legacy telecom infrastructure requiring stable component supply and long-term obsolescence management.

Supply support for XC1701PC20C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Advanced Micro Devices (AMD) was a leading semiconductor manufacturer of logic, memory, and programmable devices prior to its acquisition of Alchemy Semiconductor and subsequent divestiture of its flash memory business to Spansion.

The XC1700 series was developed by AMD specifically for Xilinx FPGA configuration, targeting industrial and telecom customers needing reliable, single-supply serial PROMs with guaranteed timing and JEDEC packaging.

FAQ

Is XC1701PC20C compatible with Xilinx Virtex-E FPGAs?

Yes, XC1701PC20C is explicitly supported for Virtex-E configuration in Xilinx Application Note XAPP151. Its 20 ns access time meets the minimum timing requirement for Virtex-E master serial mode at 25 MHz clock frequency, and its TTL-compatible outputs interface directly with Virtex-E configuration pins without level shifting.

Can XC1701PC20C operate at 3.3 V?

No, XC1701PC20C is specified only for 5.0 V ±10% operation. Attempting to power it at 3.3 V will result in undefined behavior, failed configuration reads, and potential data corruption. For 3.3 V systems, Xilinx recommends the XC18V02 or Platform Flash family instead of XC1701PC20C.

What programming hardware supports XC1701PC20C?

XC1701PC20C is programmed using AMD-compatible PROM programmers such as the Data I/O PS-3000 or BP Microsystems Model 3000, configured for the XC1700 series. Programming requires no external V_PP; all voltages are generated internally. Xilinx impact software does not program XC1701PC20C directly-it targets Xilinx-branded PROMs only.

Does XC1701PC20C support boundary-scan or JTAG configuration?

No, XC1701PC20C supports only master serial configuration mode. It has no JTAG TDI/TDO/TCK/TMS pins and does not implement IEEE 1149.1. FPGA configuration via JTAG must use a separate JTAG cable or on-board controller; XC1701PC20C cannot participate in or substitute for JTAG-based configuration flows.

Is there a lead-free version of XC1701PC20C?

No lead-free variant of XC1701PC20C was released by AMD. The device was manufactured prior to RoHS compliance mandates and uses leaded solder terminations. For RoHS-compliant alternatives, consider Xilinx Platform Flash XL (XCFxxS) devices, which are not pin-compatible with XC1701PC20C.
